Handgrip strength as a predictor of sensorimotor recovery evaluated by the Fugl-Meyer scale

ABSTRACT Cerebrovascular accidents can leave neurological, motor and sensory sequelae. To assess and monitor the patient’s prognosis, several functional measuring instruments are used, such as the Fugl-Meyer scale, which, although widely used to estimate the sensorimotor recovery, is a long evaluation that requires training. Therefore, the objective of this study is to analyze if the handgrip strength (HGS), the Timed up and Go test (TUG) and the Functional Independence Measure (FIM) can predict the results of the Fugl-Meyer scale, in order to optimize time during sensorimotor recovery assessment, both to monitor treatment responses and for scientific research. Thus, the HGS of 35 chronic hemiparetic patients was evaluated and then applied to Fugl-Meyer Scale, which evaluates motor recovery, the FIM, which evaluates motor activities and the TUG, which is an indicative of functional mobility. Statistical analysis was performed using multiple regression (r2). The HGS was predictive of motor recovery (r2=0.46; p=0.001), while mobility (r2=0.255; p=0.007) and functional independence (r2=0.054; p=0.2) were not capable of predicting the results of the Fugl-Meyer scale. After analysis, it was concluded that HGS is a moderate predictor of motor recovery after cerebrovascular accident, while mobility and functional independence are not.

摘要 脑血管意外（Cerebrovascular accidents）患者常遗留神经、运动及感觉后遗症。为评估并监测患者预后，临床常采用多种功能测评工具，如Fugl-Meyer评估量表（Fugl-Meyer Scale）。该量表虽被广泛用于感知运动恢复情况的评估，但测评流程冗长且需接受专业培训。因此，本研究旨在探讨握力（HGS）、计时起立-行走测试（TUG）及功能独立性评定量表（FIM）能否用于预测Fugl-Meyer评估量表的结果，以期优化感知运动恢复评估的耗时，同时服务于治疗响应监测与科学研究。本研究对35例慢性偏瘫患者的握力进行了测评，并依次采用Fugl-Meyer评估量表评定运动恢复情况、功能独立性评定量表（FIM）评估运动活动能力、计时起立-行走测试（TUG）反映功能移动能力。本研究采用多元回归（r²）开展统计分析。结果显示，握力（HGS）可有效预测运动恢复情况（r²=0.46；p=0.001），而功能移动能力（r²=0.255；p=0.007）与功能独立性（r²=0.054；p=0.2）均无法有效预测Fugl-Meyer评估量表的结果。经分析后得出结论：握力（HGS）可作为脑血管意外后运动恢复的中等预测指标，而功能移动能力与功能独立性则不具备该预测价值。
